[54] METHOD AND DEVICE FOR DOSING AND PACKAGING POLYSILICON CHUNKS AND DOSING AND PACKAGING UNIT
[57] Abstract: The invention relates to a method for dosing and packaging polysilicon chunks, wherein a product flow of polysilicon chunks is transported via a feed channel, separated by means of at least one screen into coarse and fine chunks, weighed and dosed to a target weight by means of a dosing balance, discharged via a discharge channel and transported to a packaging unit where a first plastic bag is filled with the polysilicon chunks and sealed, wherein this plastic bag containing polysilicon chunks is packaged by means of a further plastic bag which is formed by a shaper and is subsequently welded, wherein the at least one screen and the dosing balance at least partially comprise a hard metal on their surfaces and the shaper for forming the plastic bag comprises a wear-resistant coating.The invention furthermore relates to a dosing unit, a packaging unit and a device for dosing and packaging polysilicon chunks, which contains a dosing unit and a packaging unit.
